Fatal error

So I was on #18 of the Unreal engine c++ developer tutorial when i accidentally pressed something which made me exit my editor, I then couldn’t find the file so I made a new one. Ever since, whenever i try to compile i get the error, “c1xx: fatal error C1083: Cannot open source file: ‘triplex.cpp’: No such file or directory” I’m very new to visual studio code and c++ so I have close to no idea on how to fix this.

Because you aren’t in the directory to where you saved the triplex.cpp file. Right click the file in VS Code’s explorer and open in terminal.
